Call of Duty has always had a problem with cheaters. Whether we are talking about Warzone - the free to play battle royale, or the multiplayer, particuarly on PC. At the announcement of Battlefield 6, EA announced that Battlefield 6 will require secure boot for its anti-cheat to work, which is a major first-step to reducing the level of cheaters in the game, and now Call of Duty is stepping in and taking a page from EA.
On a new Support Page, Activision confirms that Black Ops 7 will be the first entry in the series to require Secure Boot and TPM 2.0. This is bad news if you are on older hardware, and if you are a fan of these games, might want to consider upgrading.
TPM 2.0 was a requirement for Windows 11 that was quickly bypassed, but I don’t think it will be as easy to fool EA and Activision, particuarly with how they are looking to stop cheaters entirely.
